All IPCC definitions taken from Climate Change 2007: The Physical Science Basis. This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years.Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp. Because of its length, I've broken it up into bookmarked sections for easy reference: to come back here click on 'back to contents' in each instance. Carbon dioxide and rock weathering: the chemistry Limitations to the precipitation of calcium carbonate: the Carbonate Compensation Depth The significance of weathering as a carbon-sink Deep weathering of rocks: an illustrated example from Mid-Wales, UK How breaking up minerals affects their weathering-rate: mountain-building as an accelerant Picking up signals of major weathering episodes in the geological record Weathering is a familiar process to us all.The concept of “headship” is most strongly supported in Sydney Anglican Diocese where women cannot be priests, but it divides even Christian groups.Some delegates walked out of a recent evangelical women’s conference in Sydney after a speaker suggested women should submit to men at home, in church and in the workplace where they should consider themselves “helpers” of male colleagues.The deleted sections included a primary principal’s difficulty obtaining evidence of working with children clearances from a special religious education (SRE), or scripture provider, and examples of children exposed to messages on gender and homosexuality that breached department guidelines.NSW Greens MP David Shoebridge accused the NSW Government of “sanitising” the draft report which was obtained after a freedom of information application.The Precambrian accounts for 88% of the Earth's geologic time.The Precambrian (colored green in the timeline figure) is a supereon that is subdivided into three eons (Hadean, Archean, Proterozoic) of the geologic time scale.

The Department of Education released a final report in April, after a 17-month delay, with sections of the draft report that validated scripture opponents’ concerns about the growing and unacknowledged influence of evangelical Christian groups in state schools deleted or paraphrased.The Precambrian (or Pre-Cambrian, sometimes abbreviated pЄ, or Cryptozoic) is the earliest period of Earth's history, set before the current Phanerozoic Eon.The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied.The compounds making up the vast majority of Earth's land surface - the minerals that make up rocks - are, by and large, very slow to react.As a consequence, large-scale weathering is a process that takes place on a timescale of millions of years, over which periods it constitutes a critically important carbon-sink. Because, via weathering of rocks and reprecipitation of weathering products as carbonate sediments (e.g.
